Method of interrupting electric currents.

Thelfreqnency of interruption een be vnrieoi in different Ways; riie eize of the passage in the partition between the terminale may be increased er diminiehed the passage may be of n fixed size and the terminals be brought closer together or placed farther cpurt than is -sinon/n, the electrical conductivity of the uid een be varied, end the gravity action of 'tbeiiuid can be utilized for the sume purpose. 4 Genernllyepeaking, it is found that after the apparatus besbeen in use for a short time tire 'fluid in tbe containing vessel will be lbrought to n temperature that will remain practically Stationery, whereupon the freqnency of interruption becomes uniorm, al
